LC's not returning to straight at HI-Speed, Anybody ever enhanced there LC's Options

[lotus56]

How many of you have this problem. At slower speeds LC works perfectly, at full race speed most of the time it won't return to straight position.
At first I thought car was to light in the front end so I added weight. No change. Then changed out the guides. Nope not it. Then I installed some TSRF guides on some of the cars. I am using Carrera vintage Nascar, But have found my digital Carreras do it to.
Ok no solutions yet. Opened up the LC to see whats in there and no problems there. I can only conclude that LC's need a slightly longer guide on the car to complete the return action of the mechanisim. Well I have no idea where I am going to get longer guides and I don't want to slow down when changing lanes. So I am going to install a small lighter spring so that the return position will allways have to return to straight. I think the solenoid will be able to handle the slight extra load. It appears to be very strong and your only energizing it for a micro second. Anybody got some other ideas here. I put am posting a picture here for those of you who have never seen the inside of a LC and where I might put the spring..........

I have no idea If this will work with Carrera, but In SSD land some people use a small magnet in the flipper. This was intended to keep the flipper powered while in touch with the rail.

I've had similar problems with my Pit Lane. Particularly with no-mag and/or non-Carrera (hence, lighter) cars.

I used CA glue to build up the plastic tab that the guide trips. I just had to be careful not to get any glue in the wrong spots. I sure didn't want to glue the tab in place!

OK I think I got a repair here. Spring didn't work. Solenoid is not energized long enough to make the lane change. Otherwise that would have been the ideal fix. If someone could figure out how to lengthen the energize time that would be the way to go. Anyway I didn't use a spring in the testing, I used a rubber band. Cheap, not anything special, just a rubber band, To bad it was not the fix.
After many spring adjustments, adjustments to the actual wire lane changing arm I finally I hope got it right. Using a F1 car (because it was smaller than vintage NASCAR) I could see that the LC was returning to straight but bouncing back to switch lane position.


Arrow 1 is where I used some duct tape cut to sorta fit the top of the cam, used two layers. On the cover plate in the same area I used several layers of tape to contact the cam. The purpose is to add a little friction to the cam and cover plate. Plus the cam is not the most precise fit either. Helps to reduce wobble.

2. made hole a little larger and slid solenoid farther forward to reduce ares arm could recoil back.

3. bent this spring out a little more to add more resistance to the tendency to recoil back to turn position.

OK I know duct tape and bending springs sounds hokey, but until I or someone figures out a better fix this will have to work.
I had no problem with LC until the other day. Worked perfect last week, set it up Tue. No work. I have no idea why suddenly it started. Right now I had put on a bunch of laps and its working.
